CLUTCH.

Specification of Letters Patent Ifatented Aug. 4, 1908.

Application fixed April 1a, 190s. serial 110,426,772. A

T o all whom it may concern.'

Be it knoun that I, ALBERT BORNEFELD, a subject of the German Emperor, and resident of Barmen, Germany, have invented certain new and useful Improvements in Clutches, of which the following is a specification.

This invention relates to an improved clutch in which, upon its being ut in or out of gear, one of the two shafts to )e coupled is shifted in axial direction in its bearings together with the coupling member fixed to it. At the same time a shell which is mounted in this coupling member and fixed on the shaft of the latter engages also upon the clutch being put out of gear the end of the other shaft to be coupled, for the purpose of insuring an easy and practically noiseless working of the clutch, and [its upon the clutch being put in gear a corresponding cavity of the coupling member of said other shaft.-

The`improved coupling is represented on the laceompanying drawing in which Figure 1 is an elevation of the same as put4 in gear; and Iiig. 2 a sectional elevation of the same as put out of gear.

The shafts 1 and 2 rest in bearings 3 and 4 and carry on their adjacent ends the coupling members 5 and 6. 'lhe shaft 2 is capable of beingA shifted in axial direction which can be effected by the operating lever 7 which is fulcrumed on the pivot S and shaped so as to ine'lose, and engage, with its ring 9 the collar 10 of the coupling member 6 of shaft 2.

A narrow ring edge 1 1 of the coupling member 5 of the other shaft 1 fits tpon the clutch being put in gear a correspon ing groove 12 of the coupling member 6. Within the ring I edge 11 and groove 12 respectively, the inner faces of the coupling members engage each other by means of a known gripping arrangement, 13 and 15.

In the coupling member 6 a shell 16 is mounted and fixed on the shaft 2, the bore of this shell corresponding to the diameter of the shaft l so as to engage also uien the clutch being put out of gear the en of said shaft 1 and to fit upon the Clutch being put in gear a cavity 17 of the cou )ling member 5 of said shaft 1, this having the object to insure, in spite of the vibration of the shaft ends, an easy andpractically noiseless en gagement of the clutch. y

Having fully described my invent-ion7 what I claim and desire to secure by Letters Patent isi-` A clutch comprising shafts to be coupled one of said shafts being capable of being shifted in axial direction, and the coupling members fmed on said'shafts one of said coupling members being in its inner face provided with a cavity; a shell fixed on said movable shaft and mounted in the coupling member of the latter and designed to engage u on the clutch being put out of gear the end o said other shaftand upon the clutch being put in gear to fit the cavity in the coupling member of said other shaft, for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
